BULKHEAD FOR ENGINE-FRAMES.

SPECIFICATION forming part of Letters Patent No. 790,402, datedMay 23,1905.

Application filed August 25, 1904. Serial No. 222,160.

To all whom it may concern;

Be it known that we,Ln GRAND SKINNER and J OHN O. GLENN, citizens of theUnited States, residing at Erie, in the county of Erie and State ofPennsylvania, have jointly invented certain new and useful Improvementsin Bulkheads for Engine-Frames; and we do hereby declare the followingto be a full, clear, and exact de-- scription of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, forming part of thisspecification.

This invention relates to steam-engines; and it consists, substantially,of a removable bulkhead in the engine-frame, and is designed to preventthe water leaking from the enginecylinder from entering the trunkportion of the engine-frame and there mixing with the oil usedtolubricate the engine, as well as to prevent the oil from coming incontact with the cylinder.

The features of this invention are hereinafter fully set forth andexplained, and illustrated in the accompanying drawings, in

v which- Figure 1 is a longitudinal section of the engine-frame on theline a: w' in Figs; 2 and 3. Fig. 2 is a transverse section of theengineframe on the line y y in Fig. 1. Fig. 3 is a transverse section ofthe same on the line 2 2 in Fig. 1. Fig. 4 is a top or plan view of aportion of the engine-frame, showing the cylinder-head, the bulkhead,and the cross-head supports therein. Fig. 5 is a side view in elevationof one part of the upper section of the removable bulkhead. Fig. 6 is aside view in elevation of the other part of the upper section of theremovable bulkhead. Fig. 7 is a side View in elevation of the removablebulkhead. Fig. 8 is a top or plan view of the same. v

In the drawings, A is an engine-frame provided with crossheadguide-supports B B and with an oil-chamber O, a cylinder-head A, apiston-rod A and in Fig. 1 cross-head guides D, a section of thepiston-rod cross-head E and of the stuffing-box a. in the cylinder-headA are also shown for the purpose of showing the relation of the bulkheadthereto, they,

however, being of the usual construction.

At a point between the cross-head guides D D and the stuffing-box a inthe cylinder-head IA there is provided a transverse partition orbulkhead in the engine-frame A, consisting, substantially, of atransverse wall F, having therein an opening F, the lower portion ofwhich opening is preferably made semicircular in section, substantiallyup to the plane of the center of the piston-rod A and adapted to receivea semicircular lower section G. (See Figs. 7 and 8.) This section G isprovided with peripheral flanges g, adapted to embrace the portion F ofthe bulkhead, and 5 is also provided with a recess 9 to receive packingg (see Figs. 1 and 3) around the piston-rod A When the part G is inplace, the part H, Fig. 6, of the upper section is secured to the part Gby means of screws it h and 7 also to shoulders ff on the stationarypart F of the bulkhead by means of screws f f, so that the parts G and Hare secured together around the piston-rod and also socured to thestationary part F of the bulkhead. Above the part H there is a sectionI, Fig. 5, which has its edges and bottom grooved, so that it will slidedown in the slot F in the part F and cover the part H and the jointformed therewith and complete the bulkhead, 30

as clearly shown in Figs. 1, 2, and 3. It will be observed that whilethis bulkhead forms a complete transverse wall in the engine-frame, yetthe parts I, H, and G thereof can be quickly removed from the stationarypart F, 5

so as to give easy access to the stufling-box a and be readily replacedthereon.

Having thus described a convenient construction of this invention, so asto enable others skilled in the art to construct and use 9 the same, wedo not desire to confine ourselves to the exact construction hereinshown and described, as the same may be considerably modifiedwithoutdeparting from the spirit of our invention.

Therefore what we claim as new, and desire to secure by Letters'Patentof the United States, is

1. In a steam-engine frame, a transversebulkhead, a portion of which isintegral with the engine-frame and having a slot therein, and removableupper and lower sections adapted to be secured in said slot so as toform the complete bulkhead, substantially as set forth.

2. In a steam-engine frame, a transverse bulkhead between thecylinder-head and crosshead guides a portion of which is integral withthe engine-frame, and having a vertical slot therein, and removablesections adapted to embrace the piston-rod, and be secured in the slotin the fixed section so as to form the complete bulkhead, substantiallyas set forth.

3. In a steam-engine frame, a transverse bulkhead between thecylinder-head and the cross-head guides, a portion of which is integralwith the engine-frame, and having a vertical slot therein, the bottom ofwhich is semicircular, a semicircular removable section adapted toengage the semicircular portion of said slot, an intermediate uppersection adapted to be secured to said semicircular section and toshoulders in said slot, and

an upper section adapted to close the upper Gr. J. MEAD, FLORENCESTOCKERT.
